I/O: Input/output
Power: Power supply
Notes: 1. Except in hardware standby mode, supply power to all power pins. In hardware standby
mode, supply power to RTC as a minimum.
2. Power must be supplied to VDD-PLL1/2 and VSS-PLL1/2 regardless of whether or not
the on-chip PLL circuits are used.
3. Power must be supplied to VDD-CPG and VSS-CPG regardless of whether or not the
on-chip crystal resonator is used.
4. Power must be supplied to VDD-RTC and VSS-RTC regardless of whether or not the
on-chip RTC is used.
5. At least the RTC power supply must be supplied in hardware standby mode.
6. NC pins must be left completely open, and not connected to a power supply, GND, etc.
* CKIO2 is not connected to PLL2.
